model number - svf153b1ym - doesn't appear on your website

I've been having some issues with my laptop so tried to look at the support section of your website. I typed in the model number found on the bottom of my laptop - svf153b1ym - and it doesn't appear. I tried to use the detect my model number and it wouldn't work. I have checked a number of times and this is definitely the number on my laptop.
